Answer

8 8/9     or   80/9


Explanation

7+(1/3+2/9)+(7/4-5/12)  

(1/3+2/9) = 3/9 + 2/9 = 5/9 = 5/9

(7/4-5/12) = 21/12 - 5/12 = 16/12 = 4/3

Now you have

7 + 2/3 + 13/6  = 7 + (5/9 + 4/3)

                        = 7 + 17/9

                       = 7 + 1 8/9

                       = 8 8/9     or   80/9
